Smooth microsomal cell membranes were isolated by density gradient centrifugation from normal rat liver and from the well-differentiated Morris hepatoma 5123C. The proteins were then extracted from the smooth membrane fraction and compared on acrylamide gel by the split-gel technique and by coelectrophoresis of dually labeled proteins. This analysis revealed the lack of two liver membrane compo...
